Question
If Cos t= -o.8367, find sin t and tan t when 3.2<t<6.1. Use sinsquared t + cos squared t= 1 and tan t = sin t divided by cos t
cos(t) = -.8367
(sin(t))^2 + (cos(t))^2 = 1
tan(t) = (sin(t))/(cos(t))
(sin(t))^2 + (cos(t))^2 = 1
(sin(t))^2 + (-.8367)^2 = 1
(sin(t))^2 + .70006689 = 1
(sin(t))^2 = .29993311
sin(t) = .5477
so now we have
cos(t) = -.8367
sin(t) = .5477
tan(t) = (sin(t))/(cos(t))
tan(t) = (-.8367)/(.5477)
tan(t) = -1.5277
i will ask someone else to comfirm if i have done this correctly or not, so i may get back to you on this if it isn't.
